hello, i have a sansa e280 that is stuck in manufacturing mode as far as i can tell. when it powers on, only the blue wheel light comes on, the screen does not. i have tried popping out the flash daughter board, and the e200 tool, but there is a problem. none of the computers or oses i hook it up to ever see the device, so obviously the e200tool cannot work. does anyone have any insight to this? i dont think its just the connector. i can completely remove the battery, and plug it in, it will still come on. thanks for any help -walrus
